According to legend, there is a story about Mongolian Mulan. It is said that when Mrs Mulan died, she called all the children to the bedside. She ordered someone to bring an arrow. She gave an arrow to a child to break it. The child with an arrow broke it easily. So Mrs Mulan picked up the remaining arrow and let the children break it. But even her strongest child can't break this arrow. Children, looking at each other, don't know what mother is doing this for. Mrs Mulan told the children, "Look, you are like these arrows. You are separated from each other, just like the first arrow, which is easily broken. You are United, just like the arrow behind you, and no one can break it. " Mrs Mulan died in this way. But this spirit supports the Mongols to go to the world, which shows that unity is strength.
